Magnetic Mems Device
Magnetic Mems Device
US Patent:
2007020, Sep 13, 2007
Filed:
Apr 7, 2006

International Classification:
B81B 7/02, G01P 15/105, G01B 7/00, H01L 27/22, H01L 43/00
US Classification:
073514310, 324207150, 257421000
Abstract:
The present invention relates to magnetic micro-electromechanical systems (MEMS) or magnetic MEMS devices, particularly electronic devices in which a member adjoins a base or substrate and extends from the substrate proximate to a magnetic field element having an altered output associated with movement of the member. The first magnetic field element is adapted to emit or detect a magnetic field and positioned proximate to the member, and the second magnetic field element adapted to emit or detect a magnetic field and positioned proximate to the base or substrate, such that movement of the member in a first direction by a non-magnetic force results in a variation of magnetic field strength associated with displacement of the sensor in a first direction. The invention also relates to methods for fabricating magnetic MEMS devices, transducers, sensors, and accelerometers.

Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 17/02
US Classification:
360 9701
Abstract:
In general, the invention is directed to techniques for integrated interconnects with a set of disc drives. The interconnects allow for a set of disc drives to be positioned in an array; for example, as set of disc drives may be stacked to communicate with a device through a single interface of the device. The interconnects may be formed as vias within the housing of the disc drives. Vias may produced using MEMS techniques, e. g. , electroplating, as part of the manufacturing processes of the disc drive itself.

Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/127
US Classification:
36012557
Abstract:
The present invention relates to a head having an air bearing surface for confronting the surface of a storage medium. The head includes a first pole that is spaced apart from a second pole. At least one non-magnetic spacer is positioned between the first pole and the second pole such that the first pole is magnetically decoupled from the second pole. In a further aspect, one or both of the first pole and the second pole can be elliptical in shape.

Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G01C 17/38
US Classification:
33356, 33355 R
Abstract:
The disclosure relates to micro-electromechanical systems (MEMS) and magnetic MEMS sensors. The sensors include a substrate having a surface, a first magnetic field detector positioned on the surface, a second magnetic field detector positioned on the surface proximate to the first magnetic field detector, and a third magnetic field detector positioned on the surface proximate to the first and second magnetic field detectors. Each of the first, second and third magnetic field detector is capable of detecting external magnetic fields that are mutually orthogonal along three directions. In certain embodiments, the magnetic MEMS sensors may be useful as electronic compasses. The disclosure also relates to fabricating a magnetic MEMS device, such as an electronic compass, from or on a single wafer, which includes multiple MEMS sensors.

International Classification:
G11B 5/105
US Classification:
360 9701
Abstract:
A micro-electromechanical systems (MEMS) disc drive includes high-precision and integrated components to allow for increased functionality, robustness and reduced size as compared to currently produced disc drives. Integrating multiple subcomponents of the disc drive using batch processing provides low manufacturing costs. Furthermore, using MEMS techniques, new features can be added to disc drives. For example, an environmental control component, an accelerometer and/or a thermometer may be integrated into the housing of the disc drive.
